Weather Station Sketch
I have a question about the weather station sketch:
this sketch is recommended in the forum but the DHT sensor measures no temperature changes or humidity change, during BMP180 to a temperature change responds.
I have tested the DHT-sensor with the Humidity Sketch of Mysensors under IDE> examples, the sensor reacts immediately to a change in temperature.
Only when I reboot Arduino, then DHT provides the right temperature !?
Even the official weather station sketch behaves exactly
Can someone help me, thanks in advance.
(Between pin1 and pin2 a 10Kohm resistor is built)
Hi @maxim, welcome to the MySensors forum!
Whatd does the serial debug output say?
Hi, thanks for your reply.
I see in the serial monitor (debug is enabled) that the temperature and the humidity data are alternately displayed, but no changes are displayed. If I put an ice pack on the sensor, it shows 24 degrees
But after about an hour I see in serial monitor that the temperature goes down to 12 degrees.
also the official Sketch with development library behaves the same way, which means there is no temperature change of DHT22 in serial monitor display, after a new start of Arduino I see the right temperature, I do not know what I'm doing wrong?
